CHIMNEY-FLUE LINER.

' T 0 all whom it may concern:

Be it known that I, F RED SEIrnRna citizen of the United States, residing at Boelus,

in the county of Howard and State of N ebraska, have invented certain new and useful Improvements in Chimney-Flue Liners, of which the following is a specification.

The present invention relates to attachments for chimneys, and more particularly to a liner adapted to be placed in the chimney to prevent egress of flame and sparks through crevices or crackswhich may develop in the chimney construction in its slde walls.

An object of the present invention is to provide a liner of this type which, among other features, possesses the advantage of being collapsiblev and foldable into small and compact form so that it may be easily and economically shipped in large quantities.

Another object of the invention is to provide a sectional chimneyliner of this character which embodies supporting means on each of its sections for interlocking engagement with a chimney, and which has on each section a depending flange adapted to project below the interlocking means for sealing up cracks which may result about the bottom of the liner and below any support which may be provided about the chimney. The invention also embodies the provision of a collapsible liner which may be stamped and cut from sheet metal, and which may be quickly and easily set up when ready for installation, and constitutes a permanent and secure device adapted to protect the chimney and to protect any inflammable material which may be erected about, and in proximity to the chimney.

lVith the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto.

In the drawings, wherein like symbols refer to like or corresponding parts throughout the several views,

Fig. l is a vertical section taken through a chimney mounted in the peak of a roof and showing a liner constructed accordlng to the present invention mounted in the chim- Hey;

Fig. 2 is a detail perspective view of one section of the liner;

Specification of Letters Patent.

Application filed April 11, 1921.

Patented May 9, 1922. Serial No. 460,409.

Fig. 3 is a side elevation section of the liner; Fig. is a perspective view of the liner in position'after the sections have been assembled and ready to be bent into shape for use; n

Fig. 5 isa perspective view showing fragmentarily the upturned lower end of the of an adjacent liner and Fig. 6 is an edge view of the liner knocked down and with the sections nested together for shipment.

Referring to the drawing, 25 designates a chimney of any appfcwed type which, in the usual manner, is provided'with a layer of cementor plaster 26, forming the usual lining employed. The chimney-25 is shown as passing through the peak of a roof 2?, and the roofcarries a frame 28 which surrounds and embraces the chimney 25 at a suitable distance below the top of the chimney. Frequently, settling of the chimney causes the lower part thereof to sag or drop down, while the upper part of the chimney, embraced in the frame 28, is held in proper position with the result that cracks or crevices 29 are formed immediately below the frame 28. The frame-28 is, in nearly all instances, constructed of wood as is also the rafters and other parts of the roof 27. When thecrack 29 occurs in the wall of the chimney, the cement or plaster 26 cracks and breaks with the brick work, with the result that flame and sparks passing up the chimney are free to pass out through the crack 29, and come into contact with the wooden frame 28 and roof 27.

It is found that a great many fires occur incident to this fault in the construction and settling of the chimney 25, and the present invention is designed to provide a simply constructed and handled device, which may be quickly erected in the courseof chimney construction and used for preventing the passing of sparks and fire out through the walls of the chimney beneath the roof.

The linervis shown substantially rectan- 'gular in shape, for the purpose of description, and it comprises end sections 30 and 31 and side sections 32. The sections are formed from sheet metal suitably cut and bent into the desired form, and which are of the desired length to extend, when erected in the chimney, sufliciently far above and below the peak of the roof to prevent injury thereto incident to the settling or cracking 33 which are bent at right angles in the same direction from the body plate, to'prov'ide attaching means therefor. The upper end of the body plate 30 is provided with a flange portion 34 adapted to be turned outwardly at right angles to the body plate from the position shown in Fig. 4: to the position shown in Fig. 2, for providing a top anchor to the section. The section 30 is also provided, intermediate its ends, but toward the ldwer end thereof, with a stamped and outwardly pressed flange 35 forming a lower anchor for the section.

The flanges 34 and 35 extend in the same direction outwardly from the section '30, and are adapted to be embedded in the mortar or other plastic material in the chimney wall construction, for firmly holding the liner section 30 from displacement. It will be noted that the section 30 projects considerably below the lower flange 35 so as.

to project down into the chimney to a point considerably below the lower anchor.

The other end section 31 is of similar construction with the exception of it's transverse dimensions, the same being foreshortened at opposite ends a distance equal to the thickness of the inturned flanges 33 of the other section 30. The result of such 7 construction is seen in Fig. 6 .wherein the end section 30 telescopes or fits over the end section 31 to form therewith a substantially narrow compartment in which are nested the side sections 32.

The sides 32 are in the form of sheet metal body plates having at their upper ends the outturned anchoring flanges 3 1- and provided intermediate their ends with the outturned lower anchoring flanges 35. This arrangement of flanges 34: and 35 prevails throughout the sections so that when the sections are assembled in the position shown in Fig. 4:, the upper flanges 34c register in a top horizontal plane, while the lower flanges 35 register in a lower horizontal plane which passes through the liner at a point spaced considerably above the lower end of the liner.

The flanges 33'of the end sections 30 and 31 are adapted to lap over against the inner faces of the sides 32, and side flanges 33 and the lateral portions of the sides 32 are.

apertured to the desired extent for receiving rivets'36 or the like used in assembling the sections together when setting the liner up in position for use.

It is apparent that the ends 30 and 31, when manufactured, may be nested or collapsed against the sides 32 so as to provide a package which is relatively flat and which occupies but small space, the flanges 33 being preferably proportioned with respect to the thicknesses of the sides 32 for relieving the flanges 33 from any strain imposed by lateral thrust against the ends 30 and 31 when the parts are nested together. Thus, when the device is collapsed or folded, it is capable of with standing considerable hard usage and pressure, and the devices may be stacked upon each other in large quantities without injury to the same.

The provision of the overlapping flanges 33 in the knocked down devicieprofteetsthe edges of the sides 32 and. also prevents the same from sliding one upon the other from between the ends. WVhen set up, the sides 32 are placed against the outer faces of the flanges 33 and the rivets 36 are then driven into place. The device as shipped, has its sections in flat condition such as shown in Fig. 4:, wherein the flanges 34: and 35 are unbent and lie in the general planes of their respective sections. When the device is received at its destination. for use, the ends and sides are first secured together by the rivets 36, into the form shown in Fig. 4, when the flanges 34: and 35.n1ay'then be bent outwardly and downwardly to'provide the spaced apart anchors, as shown in Fig.1.

In installing the device inthe chimney,-

the anchors 34 and 35 are embedded in the mortar or other plastic substances used in securing the bricks together, with one anchor 3&- above the horizontal plane of the peak of the, roof, and the lower anchor 35 below the lower end of the frame 28. When the liner is thus mounted in the chmney, its lower end or skirt projects, below the frame 28 to a considerable distance so that when the chimney 25 settles, its lower portion will remain sealed with respect to its upper portion by reason of the lower end or skirt of the liner. 1

I do not wish to be restricted to the size, form, and proportions of the various parts, and obviously changes could be made in the construction herein described without departing from the spirit of the invention, it being only necessary that such changes fall within the scope of the appended claims.

hat is claimed is:

1. In a sectional nesting chimney lin'er, a pair of ends and a pair of sides adaptedv to be fastenedto said ends, each of said ends being provided with a pair of inturned lateral flanges and the flanges ofon'e end being arranged to interfit with the flanges of the other end to provide between the ends a relatively flat compartment, said sides being adapted to fit in said compartment between the ends and the edges of said sides being overlapped by the flanges in the collapsed position whereby the edges of the sides are protected and kept between the ends.

2. In a sectional nesting chimney liner,

a pair of ends and a pair of sides adapted to be connected to said ends, each of said ends having a pair of inturned lateral flanges and the flanges of one end being arranged to interfit with the flanges of the other end to provide between the ends a relatively flat compartment and said sides being adapted to fit in said compartment between the ends for nesting said liner together.

In testimony whereof, I have afiixed my signature in presence of two witnesses.
